If you want to upgrade the intake, the Stealth, Edelbrock RPM and the old Ford C9OX (if you can find one) are what you want to go to. Not sure about the hood clearance on these though. The Performer is simply an aluminum copy of the intake you have now, not really an upgrade, unless you just want to loose the extra weight. Carb? Holley 570 or 670 Street Avenger or a list 80783 650 cfm Holley.
Hey D,
Do you have any personal experience with the C9OX intake?? I've never read any articles about their performance over stock, but I like using one off Ford stuff if it works well. How about anyone else? They always turn up at Carlisle, but I've never been willing to risk the $300 price tag for an experiment.
Didn't mean to hijack your thread blfowlkes, but you may also be interested in the C9OX.
I think the Shelby intake was a C9OX with Shelby markingsI think maybe Shelby had a similar intake (if they weren't using the C9) for the 69-70 Shelby GT350 Mustangs
I have two buddies who are into the circle track scene, using Windsors for power. The rules let the Fords run factory aluminum intakes where the Chevy guys can't. The guys who made up these rules were unaware that Ford made these intakesMy two friends now have a "leg up" on the Chevy guys. The looks they got were priceless when they were discovered to be running them. The C9OX is roughly the equivalent of using a Stealth or Performer RPM. If you like running factory stuff like I am, the C9OX is the only choice you have for a 351W, although, I think maybe Shelby had a similar intake (if they weren't using the C9) for the 69-70 Shelby GT350 Mustangs
... but I like using one off Ford stuff if it works well. How about anyone else?
gsxrkn, I have a Vic Jr, and the only reason I'm not using it is because I don't want to give up my shaker. I'm guessing it's costing me 20 to 25 HP using the Torker II. I like the idea of using factory parts for the stealth aspect: nobody would suspect such a stock looking motor to run so hard.
I'd be willing to lay money that the Torker makes better power than any dual plane intake, including the GT350.
You are most likely in the best situation you will get.
Swapping to DP will choke it up, while going to a more aggressive SP will lose your sleeper look and possibly the shaker.
The Torker is stock carb height.
Do you have the intake painted?
I am contemplating putting a T289 on my 302 and painting it blue to keep a stealthy look. I have a dual plane right now and it looks just like a 2v engine under the factory air cleaner.
The blue paint and stock air cleaner, I am hoping, will keep things looking kosher.
I found the test I mentioned earlier. It's a comparison between a Shelby 4V aluminum and the stock iron 4V manifold on a 351W with a mild performance cam and a 600 Holley:
RPM 2500 3000 3500 4000 4500 5000 5500 6000
Shelby 154 198 236 265 287 299 292 281
Stock 4V 161 205 246 272 290 296 290 268
Notice the spread taking place just as they let off at 6000It would have been nice if they had spun it up to 7000-7500. This confirms what I've seen all along, the high rise dual planes work everybit as well at the lower rpms as the stock intakes, but give it breathing room on top.
